Guests on the show will include makeup expert and former "large-sized" model Morgen Schick, Caroline Heldman, a professor specializing in gender and media, and former women's magazine editor Jessie Knadler. Katie will also do a hidden camera segment that examines how the public responds to a woman when she's dolled up versus when she foregoes makeup and wears her glasses.
